Abstract: A multi-position support for a multi-layer cell culture apparatus includes a primary base that rests against a support member in an upright configuration. A support surface is offset vertically from the primary base in the upright configuration. The support surface supports the multi-layer cell culture apparatus with the multi-layer cell culture apparatus located thereon. An intermediate surface extends between the primary base and the support surface. The intermediate surface meets the primary base at an interface that extends at an oblique angle to sides of the primary base. The multi-position support has a tilted configuration where the multi-position support is rotated about the interface such that the support surface is closer to the support member than in the upright configuration with the support surface supporting the multi-layer cell culture apparatus thereon.

Abstract: A cell culture system for culturing cells is provided. The cell culture system including a cell culture vessel with a cell culture chamber for culturing cells, an inlet through which liquid can flow for filling the cell culture vessel, and an outlet through which fluid can exit the cell culture vessel. The system also includes at least one fill sensor arranged to detect liquid within the cell culture vessel reaching a fill level at a predetermined position of the cell culture vessel during filling of the cell culture vessel, where the at least one fill sensor can generate a detection signal when liquid within the cell culture vessel reaches the fill level. Also included is an actuator to change an orientation of the cell culture vessel in response to the detection signal.
